The objects of the invention are herein shown as carried out in connection with a machine of the general type shown in Letters Patent of the United States to Cleal, 718,565 and 773,060, and to Von Pein, No. 1,555,534, Sept. 29, 1925, and in applications for Letters Patent of the United States of Edward J. Von Fein, Serial Nos. 293,141 and 376,088, filed April 28, 1919, and April 23, 1920, respectively.

This machine comprises a series of manipulative devices, such as keys, which operate mechanism for indicating items, en-

tering the items in one or more totalizers, and setting up type and operating a printing mechanism to make a printed record of items on a receipt which is subsequently issued by the machine. The machine also includesmechanism for printing the amount accumulated in a totalizer on a record strip kept in the machine and on said receipt.

Keys 30 .(Figs. 1 and 3) are pivoted upon atransverse rod 31, and when the forward ends of one or more of them are depressed they engage and rock a key coupler 32 having trunnions 33 seated in bearings in the side frames 34. Pivotally attached to the rear end of each key 30 is an upright member 35, each formed with a shouldered slot 36, adapted, when a key 30 is operated, to engage a transverse rod 37 on a frame 38, pivoted on a transverse rod 39, to rock said frame different distances according to the value represented by the operated key. The slots 36 are located at varying distances from the pivotal connection between the uprights and keys, to-eifect a differential rocking of the frames 38. There is a frame 38 for each denominational group of keys 30 but onl one is here disclosed in full. Each frame as attached to it a registering segment 40 (Fig. 1).

' At each operation of the keys 30 (Fig. 4), which im arts an oscillatory motion to the key coup er 32, an upright member 77 is raised and lowered to give a complete revolution to a shaft 78. The key coupler 32 is connected to the upright member 77 by a roller 79 cooperating with a slot 80 formed in the upright member 77, which is provided with a bifurcated end guided on a stud 88 and with two opposing racks adapted alternately to mesh with a pinion 83 fast on the shaft 78. A spring 86 holds the left hand rack in engagement with the pinion 78 which relation of rack and pinion is maintained during the upward movement of the member 77 by means of a flange 84 on said member and a cooperating member 85 projecting from the frame of the machine. At the end of its upward'movement the member 77 is forced to the left and the right hand rack moved into engagement with the pinion, the flan es 84 and 85 cooperating to maintain this relation during the downward movement of said member 77. A ratchet wheel 81 on the shaft 78 and a pawl 82 pivoted on the frame prevent retrograde motion of the shaft 78 after a key 30 has been depressed a predetermined amount. A cam 791 (Fig. 1) carried by the shaft 78 c0- operates with rollers 811 on a bifurcated arm 801 secured to the totalizer frame 41 to rock the pinions of the rotatable elements of the totalizer into engagement with the actuating segments. All of this mechanism is well known in the art and is shown here for illustrative purposes only.

The totalizers are of the usual form, but only the right hand or transaction and printing totalizer is here shown. It is mounted on a pivoted frame 41, and comprises a plurality of rotatable elements, each appropriate to a numerical order, as is usual in these devices. Each of the rotatable elements includes a gear 42 in mesh with. a gear 43 rotatably mounted on a shaft 44 mounted in brackets on the totalizer frame 41 and carrying. a stepped scroll 45. The lower order of rotatable elements also includes pinions adapted to engage the registering segments as the totalizer is rocked. Any

movement of the totalizer elements will be transmitted directly to the stepped scrolls 45, so that said scrolls are caused to rotate to a position appropriate to the total of the items entered on the totalizer.

Each of the segments 40 (Figs. 1 and 3) for the right hand or recording totalizer, also meshes with a pinion 49. One of these pinions is fastto the left hand end of a shaft 50 while the other pinions are mounted upon the left hand ends of telescopic sleeves 51 (Figs. 1 and 5) which extend to the right beyondv the frame of the machine proper and on their right hand ends carry printing wheels 52 for printing the detail trans- I gaged by a spring controlled pawl 68 pivoted on an arm 69 loose on an extension of the oscillatory stud 33 upon'which the key coupler oscillates. Fast on this extension and j st inside of the plate 67 is an arm 260 which carries a pin 261 extending through a slot 262 in said plate and into a hole drilled in the arm 69. At each operation of the key 30, which imparts an oscillatory motion to the key coupler 32, the pawl 68 through arm 260, in 261 and arm 69 will cause the feed rol er to rotate in a counter clockwise direction. A spring controlled retaining pawl 70 prevents' retrograde motion of the roller 65. Directly above the feed roller 65 and in contact with the same is a tension roller 71 freely mounted on a stud 72, carried by a spring controlled manually operated lever 7 3 fast on a rod 74 loosely mounted in the printer plate .67. The receipt strip 53, passing between the feed roller 65 and the tension roller 71, will be fed toward the front of the machine a distance equal to the line spacing of the printing at each operation of a key 30.

To secure a visible impression a suitable continuous inking ribbon 59 is wound around guide rollers 60 mounted in the printer frame and over an inking roller 61 mounted upon a stud 62 projecting from the printer plate. This ribbon is held taut by a tension roller 63 supported in a frame pivoted upon a rod 64, supported in the printer frame. The ribbon is fed at each operation of a recording key 30 by means of a link 75 connected to the arm 69 and to the ribbon feed ing lever 76 which carries a spring actuated pawl (not shown) for conveying rotary motion to the ink roller 61.

The total printing mechanism in general -is that described in detail in the application of Edward J. Von Pein, Serial N 0. 293,141, and forms no partof this invention. It will be briefly described here.

The total printing wheels 48 are twice the diameter of the item printing wheels 52, and contain two sets of type characters, one set be given here in connection with the electric motor operating device.

Upon operation of the electric motor or the crank handle which actuates the machine in total printing operations, the frame 102 is moved in a clockwise direction and carries with it a frame 229 mounted on a stub shaft 233 and connected thereto by a link 230. This movement permits the springs 220 to move the segment levers 221 in a clockwise direction and through partial gears 222 rotatably mounted on a shaft 223 and meshing with segments 225 on telescopic sleeves 47 carrying yokes 46, move said yokes in a counter clockwise direction, as viewed in Figs. 1 and 3, into engagement with the scrolls 45.

Referring to Fig. 5, the partial gears 222 carry segments 226 which mesh with gears 227 fastened to the left hand ends of telescopic sleeves 228 which on their right hand ends carry total printing wheels 48 (Fig. 6). As the yoke members 46 (Fig. 1) swing into contact with the stepped scrolls, the total printing wheels are rotated to positions corresponding to the total of the items accumulated in the totalizer.

At the proper time, and by the operation of the totalizing mechanism, a platen bearing member 130 will be raised, bringing a platen 131 into contact with the'type wheels 48. The platen bearing member 130 (Fig. 6) is pivotally mounted upon an arm 132, pivoted upon the stud 133 which projects from the printer plate 67. Simultaneously with the making of an impression upon the receipt strip, an impression will also be made upon the total strip 121 by mechanism not shown here.

The mechanism for giving an additional or greater movement to the feed roller 65, when printing totals, to feed the receipt strip a distance sufiicient to bring the total past the severing. means, is the same as that of the Von Pein applications referred to, and is briefly as follows: Fast upon the shaft 89 (Fig. 5) are two cams 100 and 101 which impart an oscillatory motion to a member 102 by contact with anti-friction rollers 103 and 1.04 carried on studs mounted in the member 102 which in turn is pivoted upon a shaft 105. Carried by the lower end of the oscillatory member 102 is an anti-friction roller 106 cooperating with a slot 107 in the segment arm 108, pivoted upon a stud 109 mounted in the machine frame 34 and meshing with a pinion 110 fast to an arm 111 pivoted upon the shaft 66 and having a slip pawl and ratchet driving connection with the feed roller 65. The oscillatory motion of the arm will rotate the feed roller 65, previously described.

The mechanism for resetting the totalizer to zero at the time of printing the total is identical with that described fully in the Von Pein applications, referred to, and will be but briefly described here.

The oscillating member 102 (Fig. 5), which is actuated by the operation of the 'electric .motor, is connected by said link 230 and a second link 231 (Figs. 5 and 19) to a segment lever 232 pivoted on a shaft 233 and meshing with a partial gear 234 which is pinned to the shaft 223. A segment 235, which is also pinned to the shaft 223, meshes with a gear 236 attached to a disc 237 and freely mounted on a shaft 238. The disc 237 carries a spring controlled pawl 239 cooperating with a ratchet wheel 240 which is fast to a gear 241 (Fig. 3) meshing with a pinion 242 (Fig. 5) fast to a shaft 246 which is coupled with the totalizer resetting shaft 247 (Figs. 1, 2 and 3).

So far, the construction is substantially that of the Von Pein applications referred to.

For the purpose of carrying out the objects of this invention with the mechanism hereinbefore described, an electric motor is operatively associated with the total printing mechanism and means is provided for locking the item entering means and releasing the motor when it is desired to print a total of a transaction which means is actuated by the total printing mechanism to arrest the motor and to release the item entering means.

An electric motor 140 (Fig. 6), which primarily serves as an actuator in connection with the printing of totals on the re ceipt strip and also on the total record strip, is mounted on the right hand side of the machine frame and directly under the printer. The motor drives the printing mechanism through a clutch device, which is well known in the art and is shown in Figs. 15, 16, 17 and 18 for illustrative purposes only. Fast to the clutch shaft 141 (Figs. 6,14 and 15) is a pinion 142 which meshes with an intermediate gear 143 freely mounted upon a stud 144 projecting from the side frame 34. The intermediate gear 143 also meshes with a gear 145 fast on the driving shaft 89. These gears make one complete revolution during each operation of the total printing mechanism.

The total printing mechanism is normally retained in an inoperative state by a swinging member 146 (Figs. 14 and 18) shaft 89. This member 146 is formed atits lower end 147 to engage with various members of the driving clutch for opening and closing the circuit switch and stopping the total printer driving shaft.

The starting of the motor is manually controlled by a lever 148' (Figs. 9 and 14) freely mounted on a stud 149 projecting laterally from the side frame 34. Pivoted on a stud 150 mounted in the lever 148, is a downwardly extending'member 151 guided near its lower end by a stud 152 mounted in the side frame of the machine and projecting through an opening 153 in member 151. A spring 154* attached to the pivot stud 149 and to a pin 155 projecting from the member 151, normally holds the lower side of the opening 153 in contact with the stud 152. The lower end .of the member 151 has an angle edge 156 which contacts with a pin 157 projecting from the side frame of the machine, which, as the lever 148 is depressed, causes the member 151 to swing slightly in a clockwise direction. As a shoulder 158 on the member 151 moves past a flat sided pin 157 spring 154. will cause the member 151 to latch under the pin 'and retain the same in such position until near the end of the total printing operation.

Two spring controlled levers 159 and 160 (Figs. 5 and 14) are freely mounted upon a stud 161 projecting laterally from a horizontal bar 162, and are normally in contact with the flat side of the pin 157. On the forward end of the lever 159 is a formed ear 163 which overlaps the forward end 164 of the lever 160. An ear 165 formed on the member 151 will, when the motor starting lever 148 is depressed, contact with the ear 163 and cause both levers 159 and 160 to swing on their pivot 161, lowering the end 164 until it is-below the fiat side of the pin 157, when the bar 162 will move toward the rear of the machine under the tension of a spring 166. In this position the end 164 of the lever 160 will rest against the flat side of pin 157, and the formed ear 163 on lever 159 will be to the rightof the formed car 165 on the member 151. The horizontal bar 162 is supported upon two studs 167 and 168 which extend into slots 169 and 170 formed in thebar 162. The right hand end 175 of the bar 162 engages with a pin 176 projecting from the swinging member 146.

The downward movement of the motor starting lever 148 releases the lever 160 from the stud 157 which allows the bar 162 to move to the right (Fig. 14), swinging the member 146 a sufiicient distance to disengage the end 147 from the motor driving clutch thereby closing the circuit and permitting the motor to operate the total printing mechanism as will be hereinafter described. As the intermediate gear 143 revolves in a clockwise direction, a cam 177, fast to the gear 143, will engage with a roller 178 carried by the lower end of the swinging member 146 and move the member forward to a position where the lower end 147 will engage with the various clutch members to break the circuit and stop the motor and also the total printing mechanism. As the member 146 swings forward the horizontal bar 162 moves with it, carrying the levers 159 and 160 forward. During this forward movement the ear 163 will contact with the right hand side of the ear 165 on the member 151 and swing the member on :its pivot 150 thereby disengaging the shoulder 158 from the pin 157, to allow the motor starting key 148 to be returned to its normal position by the action of the spring 154. The forward movement of the bar 162 will also allow the end 164 of the lever 160 to assume its normal position to hold the bar 162 until the motor starting key is again pressed downward.

The lever 160 will be returned to its normal position even if the starting key 148 is held in depressed position. It is therefore impossible to get repeat operations of the total printing mechanism by holding the starting key depressed.

The swinging member 146 (Fig. 18) normally retains a cam plate 180 against the tension of a spring 181,0ne end of which is attached to a pin 182 projecting from a disc 183, the other end being attached to a pin 184 projecting from the cam plate 1.80. As the cam plate 180 is released it moves in a clockwise direction to the extent of the length of a slot 185 in the cam plate through which the pin 182 passes to engage the end of the spring 181. This initial movement of the cam plate 180 (Figs. 10 and 11) closes the switch member 186 which causes the operation of the motor. Cooperating with the cam plate 180 is a roller 187 carried on a yoke 188 which is fulcrumed on a rod 189. The yoke 188 has an arm 190 cooperating with a roller 191 carried on a pivoted arm 192 which brings together the contact points of the switch member.

The cam plate 180 when released by the swinging member 146 changes its relation to the disc 183 so thatthe depressed part of the circumference on the cam late is opposite the'full diameter of the time 183 which, as the plate and disc rotate in unison, will form a complete circumference of full diameter and retain the yoke member 188 (Figs. 10 and 11) in operated position until the cam plate is stopped by the return of the swinging member 146 to its normal position near the end of the total printing operation. A plate 193, fast to the cam plate 180, cooperates with the swinging member 146 to retain the cam plate in its normal position. Near the end of the operation a projection 194 on the swinging member 146 engages a shoulder on the disc 183 which is fast to the pinion 142 and the motor clutch cam 195 and thereby stops the total printing mechanism after it has completed its operation. The projection 194 also engages a shoulder on a disc 196 which carries the rollers shown in Fig. 18 and thereby breaks the driving connection between the shell 197 and the clutch cam 195. As the motor and driving clutch are similar in construction to those shown in'the Letters Patent to C. F. Kettering and W. A. Chryst, N 0. 1,144,418, granted June 29, 1915, only a brief description is here given.

To prevent a simultaneous manipulation of both the item entering keys andthe motor starting key, a device is provided which will lock either element while the other'is being manipulated. Fast on the shaft 78 (Fig. 14), which makes a complete revolution each time the item keys are operated. is a disc 200 having a notch 201 adapted to cooperate with a square pin 202 projecting laterally from a pitman 203. The rear end of the pitma-n is bifurcated and embraces the shaft 78 to be guided thereby as the starting key is operated. The forward end of the pitman is pivoted on a stud 204 mounted in an arm 205 extending downward from the motor starting key 148. As soon as the shaft 78 starts revolving, the slot in the disc moves out of alinement with the pin 202 thereby preventing an operation of the motor starting key. In the event that the motor starting key 148 is depressed before depressing any of the item entering keys 30, the pin 202 will enter the slot 201 in the disc 200 and thereby prevent rotation of the shaft 78, which, through mechanism previously described, will lock the item keys against manipulation.

In addition to the electric motor for operating the total printing mechanism, a manually operated crank 208 is provided, which will be but briefly described here as it is fully described in the Von Pein applications referred to. The crank 208 is freely mounted on a stud 209 projecting from the printer plate 67, this crank is connected by means not shown herein to one end of a sleeve 210, the other end of which carries a pinion 211 meshing with a gear 212 fast on the driving shaft 89 (Figs. 9- and 12). The operating crank 208 connects with the sleeve 210 through a clutch 213, and there is sufiicient space between a countersunk shoulder on the crank (not shown) and the head on the stud 209 to allow the crank to be moved laterall out of engagementwith the clutch mem er to allow the electric motor to operate the mechanism without rotating the crank 208. Referring to Fig. 12, the crank is shown clutched with the sleeve 210.

A roll 216 on an arm 217 pivoted on a stud 133 is drawn into engagement with a cam 218 fast on the driving shaft 89 by means of a spring 215. The cam and spring cooperate to equalize the work of the total printing crank to permit of a nearly uniform rotation being given to the driving shaft 89. All of which is fully described in the Von Pein application Serial No. 376,088 referred to.
